TO ALL l.VI-IOM Il MAY CONCERN: l

Be it known that I, CHARLES T. HARVEY, of Tarrytown, in4 the county of Westchester, in the State of New York, have invented anew and useful Improvement in Elevated Railroads; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled `in the art to malte and use the'samc, reference being had to the accompanying drawing forming part of this specification, in which drawing- Figure lis an elevation of my improvement. V A Figure 2 is a plan view of the part below the sidewalk, the pav`cmenthaving been removed.- Figure 3 is an elevation, inside view, of the said improvement. i l Figure 4 is a plan view of the track of. the elevated railroad, and of the elevated sidewalk which I combine therewith.

Figure 4 also shows, in red outlines, how the endless propelling-cable is returned to the place whence it starts.

Figure 5 is an elevation, in cross-section, of the track, with the operative and return-cable guides, thelattcr being shown in red.

Figure G, sheet 2, is an elevation, showing how my elevated sidewalk is carried over an intersecting cross-street.

Figure 7 is an elevation at right angles to thatshown in fig. 6, and

Figure 8 is a. plan thereof.

This invention relates to eievated railroads, and-consists, among other things, in a no vel method of supporting or lforming foundations for the columns of an elevated railroad where it goes over vaults, cellars, or other sunk'en places, or over sewers oro'ther subterranean works; and it also consists in combining with the columns a sidewalk that extends to the buildings of any street where the elevated railroad is erected.

Other features of the invention will be mentioned as the description proceeds.

. In building an elevated railroad uponstreets, as well as private property, where there are vaults, cellars,

er excavations, beneath the surface ofthe ground, it'is desirable to avoid building piers or foundations therein, er otherwise disturbing them, and it is also desirable, in case of' sewers, water and gas-pipes, and other subterranean works, to avoid interference therewith. p

In order to avoid interfering with orv disturbing these or other subterranean works, and yet construct an elevated railroad over the same, in a'irmand secure manner, I have invented the following method of supporting, sustaining, and securing the columns. v l

The letter' A designates a vault, appertaining to a. building, whose front wall is shown at Bf The front wall of the vault in shown at C.

The letter D designates the cover of the vault, which c'over constitutes `also the pavement of the streetsidewalk for pedestrians.

Below the sidewalk or cover I), (or else embedded in the same, ifthat method of construction is prcferred,) I place a strong frame, composed of beams, E, of iron, er other suitable materials, which extends across the vault, and beyond the same into the roadway, but beneath its surface, and rest upon the walls B and C.

In order to avoid' interference with the curb-stone of the sidewalk, or with the gutter or roadway of the struct, the beams E, after they pass the eolumns, are deflected downwards from a horizontal line until the gutter is passed, when they are bent back to a horizontal line. .'Ihcir outer ends rest on one or more blocks or sleepers, 4l", embedded in the ground, proper' precautions being-taken to preventdisplacemcnt of the beams in any direction. Instead of deileeting the beams in this manner in order toget. below the gutter and curb-stone, I eau make them in two divisions, an upper and lower one, whereof the upper one shall extend to` or `nearly to the curb-stone, and shall rest on the lower one, whichwill extend thence beneath the curbstone and gutter, andas far into the ground as is required; the t-wo divisione being firmly bound together by the sume bolts that secure the base of the columns to the beams.

In this example l have shown the beams deflected, as in iig. 3, so as te clear the bottomof the curb-stone G, and also clear the gutter of the street.

'lhe letter I designates the base-plate of the column J, which` base-plate rests upon the pavement D, and is firmly secur'ed thereto, and to the beams E, by means of bolts, K, and n. plate or block, L, that goes under the beams, thelboltsK going through both the plates 'I and L, and through the pavement D7 in such a manner as to enclose and bind the beams and pavement between said plaies. The bolts can, if desired, also zo through the beams, instead ot' only going between and outside of them, as shown in the drawing.

The'base-plate I ofthe column is, in this example, let into a depression or countersink made in thu pavcment or vault-cover D, so as to let thev surface of the plate ccm'c {iush with said pavement.

Inorder to relieve the column and structure of the railroad fromv unpleasant jarsand noise, and to'preserpvc the pavement from injury, I interpose a cushion, N, of wood, rubber, or other suitable'elastic substance,bet-ween base-plate I and pavement D. y

Where there is no objection to placing the foundation or base of a. column in a vault, such foundation er base can rest on the iloor of the vault, vor be sunlcbelowvsuch loor.

The letter M designates an elevated sidewalk, which I combine with the columns of the elevated railroad. The pavement of such sidewalk is made of any suitablematerials, but I prefer transparent or translucent materials,.-.so that' the transmission of light to the sidewalk below will' be obstructed as little as possible.

The outer edge of the elevated sidewalk is connected tothe columns, and thetraclof the elevated railroad, and its inner edge is connected to the walls of the'buildings that line thestreet, and at places where ther-c are no buildings the inner edge is supportedby a wall .or other structure built for that purpose.

tThe' slabs ot`- the pavement are, in this example, supported at their ,outer edges on theflange of'one of the l rails at the track, adat their inner edges on a rebated'heam, which may be of metal, that 'extends along the walls of the buildings, whle'their sides rest onrebated beams, O, that pxtend from the track ofthe railroad te the opposite buildings, and which beams O are firmly secured tothe track and to the buildings,.so that they forni .braces for the track as well as supports for the sidewalk.

In figs. 6, "I, und 8, I have slro'wn how I carry the elevated sidewalk, M, over e.- cross-street by means of a bridge, It. i

J J' are supporting-columns, placed in the cross-street, or near to its corners, and the beams O, which, in sheet 1, are seeuto extend from the truck te the buildings, in sheet 2 extend from the track to the sai'd lateral columns J J', und to the beams of frame 1t which connect said columns J J to each other, and are combined with other beams, O', to compose a frame of sucieut strength for the required purpose.

The structure is properlybraced with braces P, and I place `a truss-balustrade, Q, at the edge of the sido-l walk, and another at the opposite side of the bridge along the track.

It will be observed that I thus form a bridge over a cross-street with the aid of only two supplementaryV supporting-columns, J J', combined withv the ordinary columns of the railroad, and with the track thereof.

In iig. 5,"and also in iig. 4, I show in red outline a return-cable guide for the propelling-cable, arranged alongside of one of, the rails. v

The return-cable guide is here shown reversed from the position of the direct guide, and the cable is brought to alrever'sc position by suitable pulleys on a twisted guide at the ends of the course.

rWhat I claim as new, and desire to secure by Letters Patent, iss- Theeombination of' a supporting-column of an elevated railroad with .beams E,'to which it is secured, and with the pavement or cover D, in such a manner that the column is supported above cr over vault A, substantially as und for the purpose described. v
